The 3 numbers indicate the server load for 1, 5 and 15 minutes. As for what server "load" indicates

basically the server load is a number. This number is usually under the x.xx format and can have values starting from 0.00. It expresses how may processes are waiting in the queue to access the processor(s). Of course, this is calculated for a certain period of time and of course, the smaller the number, the better. A high number is often associated with a decrease in the performance of the server.

Knowing what the value of the server load is not very important though. Knowing how to interpret the value is what counts. Unfortunately, there's a lot of debate on how to actually interpret it, even among web hosting company owners.

One thing is sure however: all of them consider a server load of 0.xx as safe. As long as most of the time the server load is under 1.00, you should not notice any problems like your website being slow (unless there are some networking related problems somewhere between your computer and the server).

The uncertainties come when the server load has values over 1.00. Most web hosting company owners apply the following rule: if the server has a single CPU (central processing unit), a server load higher than 1.00 is not good; if the server has two CPUs, a server load over 2.00 is not good and so on.
